Claude's training data has a cut-off, so asking it what is good right now gets you last year's answer. Last 30 Days turns Claude into a research agent that searches Reddit, X, YouTube, Hacker News, Polymarket, GitHub and the web for the past month.
Results are scored by real signals such as upvotes, likes and betting odds rather than by an editor, then synthesised into a grounded summary with citations so you can check the sources.
It also works in Codex, Cursor and claude.ai, and it is one of the most-starred Claude skills on GitHub for good reason.

In Claude Code run /plugin marketplace add mvanhorn/last30days-skill, then /plugin install last30days. Reddit, Hacker News, Polymarket and GitHub work straight away; run it once and a 30-second wizard unlocks X, YouTube, TikTok and others.
